Has anyone use other ad converter with  AmaSeis?

Hi Ted,
 
    Yes, their old 12 bit DI-154RS ADCs.
 
    I would guess others  would work, but AmaSeis requires you choose one 
of the seven.  Which one  would you choose, if the one you are using is not 
on the  list?

 
    The DI-194 is only 10 bit, which is marginal for  seismic recording.
    The DI-158U is 12 bit - about the minimum  practical.
    Note that the very expensive Dataq ADCs are only 14  bit. Dataq don't 
seem to know anything about signal averaging.
 
    AmaSeis only accepts up to 16 bit signals, in ASCII  decimal characters.
 
    AmaSeis requires an input and control  interface program - only those 
on the list will work. 
 
    Regards,
 
    Chris Chapman
